High-pressure valves from SKG Pneumatics Inc

High-pressure valves are manufactured according to the latest international designs, using the latest advanced technology and a strict quality control system. These valves are exceptionally robust, robust, and durable. They are designed for a waterproof seal, ease of use with integrated quality and integrity for long service life. SKG Pneumatics Inc is specializing in firefighting equipment and industrial valves suppliers. If you are searching for industrial valve suppliers then your search destination ends with SKG pneumatics.

High-pressure valves are manufactured in Gate and Globe valve types.

  • Gate valves: It is the most common valves in use today, especially when the uninterrupted flow is required, as the valve fully retracts into the bonnet, creating minimal pressure drop when the valve is in the open position. Gate valves usually are intended for use in isolation applications.
  • Globe valves:   The main advantage is that a globe valve opens faster than a globe valve because the disc only needs to move a short distance from its seat to allow full flow. It is an advantage in case of frequent valve operation. The disadvantage is that the fluid has to change course, which increases the resistance to flow and generates turbulence. It results in a higher pressure drop through a globe valve than a gate valve. Globe valves are designed to close, open, or restrict flow in a pipeline.
  • The pressure seal cap:   Another very effective type of cap construction, apart from the standard bolted cap type in a gate valve, is the seal cap. This construction is adopted for valves for high service at very high pressure. The unique feature of the pressure seal cap is that the seal of the body-cap seals improves as the internal pressure in the valve increases, compared to other constructions where the increase in internal pressure tends to create leaks in the body-cover gasket.

SKG pneumatics is the topmost reputed firefighting equipment dealer and has been top-ranked in manufacturing & supplying high-pressure valves for many years.

Applications of High-pressure Valves

  • Boilers of steel industries:- In Iron and steel industries where boilers are used at high pressure, high-pressure valves are essential to keep safety at the workplace. 
  • Power plants and Chemical factories:- Certain chemicals are stored at high pressure as they can be dangerous at low pressure. Hence using reliable and efficient high-pressure valves can decrease the risk factor.
  • In sugar factories:- Manufacture of sugar involves high pressure in the boiler which can easily be regulated using high-pressure valves. Our valves can function properly in water, aggressive environment as they are made from chemically inactive material and do not contaminate or react with the fluid passing through them.

What is Valve Automation? 

Industrial valves are mechanical devices that are used in various industries to control the flow of fluids and gases. 

Valve automation is the process of adding a valve actuator and control system to the valve and can be powered by electric, human, hydraulic, or pneumatic energy. 

Just like valves, there are different types of valve automation.  

Types of Valve Automation

  • Manual: There are various ways to use valve automation via manual energy. This includes hand wheels, levers, and gears. Since it is manually operated, it isn’t as costly as other methods. However, it is impossible to operate larger valves manually because of the high thrust requirements. There can also be a safety issue if the valve is located in remote or hazardous environments. 
  • Pneumatic: Pneumatic valve actuators use gas or air pressure as its power source to turn the valve on or off. Because of their simplistic design, they require minimal maintenance. Besides, they can be even used in areas with extreme temperatures. 
  • Hydraulic: Much like Pneumatic valve actuators, hydraulic valves use fluid pressure as its power source. Hydraulic actuators are suited for high-force applications, and they can produce more significant force than pneumatic actuators of the same size. 
  • Electric: The electric actuator converts electrical energy into torque to operate the machine. Out of the four types, electric valve actuators offer the highest precision control positioning. Besides, they are non-toxic, quiet, and energy-efficient. They are expensive and not ideal for applications that require high speed or failure modes. 

Difference between Valves & Actuators

If you have worked with industrial valve suppliers, you might know that both valves and actuators play a crucial role in automating process control. 

A valve is used to control the amount of fluid flowing through a pipe/machine. However, you must

A valve is used to control the amount of fluid flowing through a pipe/machine. However, you must set it either in a specific position or control it manually. Actuators, on the other hand, is controlled by a computer system that uses different sensors which dictate the action of the actuator and therefore the valve.

Solenoid Valve – Working process of solenoid valve

A solenoid valve is an electro-mechanical valve that can be used to control the flow of liquid or gas. The main components of the solenoid valves consist of a valve stem, valve disc, valve body, valve boot, valve seat, stop washer, centring washer, plunger, coil, and a cover nut. It is commonly used in hydraulics & pneumatics to shift two way and 3-way directional control valves and some pressure control valves. The basic function of the solenoid valve is to shut off, distribute, and release fluid.

Working process of the solenoid valves

The main functional components of solenoid valves are the coil, plunger, and sleeve assembly. When the orifice in the solenoid valve is open, then it allows the flow of fluid. However when it is closed, then it prevents the flow through the valve. To open the orifice of a solenoid valve plunger is used, which raises or lowers within the sleeve tube by energizing the coil. Once the solenoid coil is energized, the resultant magnetic field raises the plunger, enabling the flow. When the solenoid coil is energized in a normally open valve, the plunger seals off the orifice, which in turn prevents flow.

Application of Solenoid valves

  • Hydraulic action:- Solenoid valves are designed specifically for controlling hydraulic operations effectively.
  • Controlling air pressure:- Solenoid valves are used for mixing and distributing the air effectively and hence, effectively control the air pressure.
  • Treatment of water:- As it can purify the smallest particles and dust, they can be used effectively in the RO purifier as well.
  • Fuel supply: – A solenoid valve is used in fuel valves to control the oil in vehicles. Highly efficient solenoid valves are leak-proof and can control the flow of oil effectively.
  • Blood analysis instrument:- Solenoid valves are also used in blood analysis instruments. These instruments need to control the flow of the blood properly, and solenoid valves are designed specifically for this purpose.
  • Machines and plant engineering:- Solenoid valves are commonly employed in manufacturing companies or oil refineries. They are often used to control the temperature of heater or furnace, firing systems, etc.

Highly Durable and Reliable Solenoid Valves

Features of Solenoid valves

It consists of a movable armature made of an iron alloy and attached to the valve needle, all sealed into the valve body. The coil is wound around the valve housing that contains the armature.

Difference between Pressure Relief Valves and Pressure Safety Valves

A pressure relief valve is one that is used to limit the pressure in a system within a specific set level. However, a pressure safety valve actuates automatically to release excessive pressure. Relief valve opens only when the pressure reaches the specific set pressure limit and is usually operated by an operator. It does not require operator assistance to release excessive pressure.

The similarity between the pressure relief valve and the safety valve is that they both are spring-loaded valves. Usually, the valve is forced shut by the spring. When the pressure increases, the force of the spring has overcome that forces the valve to open.

Classification of the Pressure Relief Valves

Pressure Relief Valves are essential for controlling the flow rate of fluid, thereby facilitating the practical use of the system and providing additional safety to pressurized vessels or systems. There are three types of Pressure relief Valves.

  • Safety valves: – A pressure valve that is used with compressible gases, steam, and air services.
  • Relief valve: –  A valve that is used in a hydraulic system as pressure over sill devices. They can further be into adjustable relief valves and safety relief valves. They are usually used in naval ships for generating thermal electricity.
  • Safety Relief valve: – A valve that is used either for liquid or compressible fluids in a pressurized vessel is called a safety relief valve. These are generally used in boilers.

Classification of Safety Relief Valves

  • Conventional(spring-loaded):- The main components of traditional spring-loaded safety relief valve are the nozzle, seat disc, disc holder, bonnet, spring, set pressure adjusting screw, body, and blowdown adjustment ring.
  • Pilot operated:-  The main component of pilot-operated hydraulic valve is inlet from the system, orifice, main spool spring, dart, pilot spring, adjustment screw, pilot drain, the skirt of the spool, and
  • Balanced bellows:-  The essential components of Balanced bellows relief valve are nozzle, body, adjusting ring, disk, seating surface, bellows, balanced piston, bonnet, spring, adjusting screw, stem, and cap.

SKG Pneumatics is the best supplier of industrial valves in Delhi. The company has been into pneumatic industries for several years. The company manufactures different types of relief and safety valves that can be used in the industrial production unit. The pressure safety relief valve can prevent damage to property, life, and environment to a great extent and shall be used in every industry for additional safety. The pressure relief valves can be used in pressurized vessels, boiler, and other pressurized systems.

Valve Design and Working Principle of Butterfly Valve

A butterfly valve is used to isolate or regulate the flow of a fluid. It can be used for a wide range of applications such as water supply, wastewater treatment, and fire protection, for chemical and fuel industries and many more. 

Butterfly Valve Working Principle

It is based on the quick shut off principle. The disc of the valve is placed in the center of the pipe which allows a rod to go through it to an actuator, on the outer side of the valve. The disc remains parallel or perpendicular to the flow. A pressure drop is introduced by the disc upon the flow even when open. 

It open or closed when the disc is rotated a quarter turn and hence it is also known as a quarter-turn valve. There is a metal disc on the rod and when the valve is closed it blocks the passageway by giving it a quarter turn. This metal disc is known as a butterfly. It is the most important component of the valve. 

Butterfly valve classification

Butterfly valves are quick to open type valves used to stop, regulate and start the flow of the fluid. A gearbox type actuator is attached with large butterfly valves and a hand wheel is connected to the stem of the valve via a gearbox. The butterfly valve is classified into four types.

  • Centric Butterfly valves: Centric butterfly valves are also known as soft seated valves. They are used for low- pressure and non- critical applications in gate and ball valves. They are very cost-efficient and easy to install. Centric butterfly valves are also very lightweight.
  • Motorized butterfly valve: Motorized butterfly valves are used to control the media flowing through the pipelines of the system. By changing the position of a round disc within a pipeline, it starts operating. They are available in many different sizes and they can be fit into any type of specifications. 
  • `Pre-insulated butterfly valves: Pre-insulated butterfly valves avoid the cost as well as manpower for insulating the valve after installation. They are made up of very fine quality materials. They are of very simple design and enhance durability. Pre-insulated valves have a long service life and they are crack resistance.
  • Wafer type butterfly valve: wafer type butterfly valve is very easy to install into the system but it does not work as an isolation valve. It is placed between pipe flanges and the flange bolts encircle the valve body.

Butterfly valves design

The butterfly valve comes into two designs, centric and eccentric. The only difference between these two designs is, in centric butterfly valve stem is placed in the center of the disc and disc is placed in the center of the bore. Whereas in eccentric butterfly valves, there can be more than one stem placed offset from the center.

Butterfly valve does not require high maintenance and hence widely used in industrial applications. They also require a little space and it is very easy to open them. 

Components

There are four main components of a butterfly valve: body, disk, stem, and seat.

1. Butterfly valve body

The body of the butterfly valve fits between two pipe flanges. It is one of the main components of the butterfly valve. Lug and wafer body design are most common among them.

2. Butterfly valve disk

The disk is used to stop the flow of the liquid. The disk of the butterfly valve has a number of variations in its design and orientation to improve the flow, sealing or torque.

3. Butterfly valve stem

 It is available in two design one- piece shaft or two-piece design. For the proficient selection of the material with respect to its cost as well as mechanical properties, it is confined from the media.

4. Butterfly valve seat

How Fire Sprinkler System Work?

Fire is an ultimate nightmare for those who run a store or warehouse. Just imagine your building is stocked with furniture and other flammable items and a fire breaks out at night when no one is around. No need to worry we are here with a fire- fighting system which can react the moment trouble strikes. It has a sounding alarm and an automated sprinkler system to put out a fire as quickly as possible. Fire sprinklers are not for business use only they are also worth having in homes. This is one of the best fire protection systems which have protected life and property for over 100 years.

A fire sprinkler system seems to be a simple system made up of pipes with sprinkler head that deliver water to a fire. But it is a complex system that is carefully designed, installed and tested. An automatic fire sprinkler system works when high heat triggers the sprinkler system. The air above the sprinkler heats rapidly when a flame ignites. When this hot air reaches a sprinkler’s head, it triggers a chain reaction. The sprinkler is filled with a glycerin-based liquid expands when it comes in contact with the hot air and the sprinkler head activates. A fire sprinkler system is ready to install after the designing process.

Fire system installation process is quite simple and it is done by the pipe fitters at the construction site. There is a need of commercial sprinkler system in commercial buildings as a fire could seriously injure or kill employees or customers, damage property, destroy paper records. A fire sprinkler system makes your business safer. The automatic fire sprinkler system detects the fire and it is far way better than the spray that is used to extinguish the fire.

So if you are also willing to make your business safer than automatic fire sprinkler system is the right choice for you. SKG Pneumatic Inc is the one stop destination for complete range of industrial products. We are one of the leading fire fighting equipment suppliers. You can contact us for any kinds of fire equipment.

Types of Gate Valve and its Specifications

A gate valve is a linear motion valve that is used to start or stop the flow of the fluid in piping. There is a gate or wedge type disk which moves perpendicular to the flow which directs the flow to stop or start. In any process plant, the gate valve has the most common use and are suitable for both above-ground and underground installations. A gate valve is also known as a sluice valve. It is very easy to open it, one just have to lift the gate out of the path of the fluid. It does not require a wide surface; it fits in a very little space along the pipe axis. It requires a 360° surface contact between disk and seat to achieve proper sealing. A Gate valve is made up of certain parts that allow it to function properly. Valve’s body or shell is the most principal part of this particular valve which can connect inlet and outlet pipes in a piping system. Some other parts of a gate valve are as followed. Bonnet, Solid Wedge, Body seats, Stem, Back seat, Gland follower, Gland flange, Stem Nut, Yoke Nut, Handwheel, Hand wheel nut, Stud bolts, Nuts, Bonnet Gasket, Lubricator, Packing. All these parts allow the Gate & sluice valve to function properly.

Now let’s discuss the main types of gate valves.

 

1. Knife Valve   

Knife gate valves contain a very high quantity of suspended liquids. It is mainly used for on – off and isolation services in systems. Knife valves are the best suitable for working in some of the harshest environment. These valves should be used for the applications which require a completely open or completely closed position.

2. Brass Gate Valve   

Brass gate valves are the perfect fit for the applications where corrosion is a serious concern. It is considered as the most durable gate valve. It has a very high capacity to tolerate high temperatures as well as high pressure.

3. Slide Gate Valves 

The main purpose of the slide gate valve is to shut off the flow of product from discharge points such as dry bulk storage bins, silos, conveyors, etc. It is the best choice for industrial works.

4. Non-return Valves

Applications of Valves in Water Industry

In industrial engineering, manufacturing and scientific communities, there is a vast use of valves. The main objective of the valve is to control the flow and pressure of water and to release air from the water system. Valves play a very ample role in the water industry.  Water valves are used in many parts of daily mechanical devices such as HVAC and water system in an office.

 

Most Common Valves Found in the Water Industry and their Characteristics

 

1. Gate Valves

Gate valves are the most common valves found in the distribution system. Gate valves are mostly used for the on/ off control. Gate valves prevent the flow of the liquid in both directions. They are very easy to install and to maintain. Gate valves are cost efficient and they are mostly used in petroleum industries because of their abilities to cut through liquids.

2. Butterfly valve

Butterfly valve also known as quarter turn valve because it provides 90-degree rotary motion for stoppage. They often came in large sizes but short in length and are of very light weight. They posses very low torque requirements.

3. Ball Valves 

Ball valves are considered as ideal for pump check services. In ball valves a ball rotates between two circular seats which are made up of a kind of PTFE and co- polymer. They exist in a small size range between 1/2” to 12”. These valves are used in higher pressure applications. Ball valves can be operated with less torque than gate valves and has small dimension and are lighter in comparison of gate valves.

4. Plug Valves

Plug valves are used to control the flow by rotating the conically tapered plugs inside the valve body. They came in a very simple design with few parts and their maintenance and repair is very easy to do. They contain very low head cost and comes drip tight closing.

5. Regulating Valves

 Regulating valves are designed to enable the direct control of flow rate and the considerable control of process quantities i.e. reduces the flow/ pressure. A high head loss can be tolerated by regulating valve and they came with multiple control scenarios. These valves are installed on trunk or industrial pipelines and it consists of a regulating unit which varies the flow cross-section.

6. Air/Vacuum Release Valves

 As it is clear from the name that these types of valves releases air during the filling and testing of pipe and it also releases air that naturally accrues in pipes. During draining it allows air into the pipe and it also assures the pipeline carrying capacity.

Functions and Applications of Automatic Balancing Valve


Automatic balancing valves are used in heating and cooling systems where water flows through the system. Balancing valves are used to ensure the correct distribution of water flow within the system. Water flows from one system to another. When water is flowing in this way it is possible that the pressure is not consistent enough. This can lead to an inconsistent output. To control and regulate these valves are used.

Functions of balancing valves

When Check Valves & Non-return Valve are used in hydronic systems, it ensures a proper design flow within the system leading to a better working of the cooling system where it is being used. Apart from this the other functions of automatic valves are:

  • They work as pressure independent control valves and help to limit flow to achieve the desired rate of flow.
  • It is an automatic valve and does not require manual intervention. This makes it simpler to use and there is no dependence on external persons.
  • Ensures the best flow rate that can improve the efficient working of the system.
  • Valves help to eliminate vibration and noise from the system where they are used.
  • Automatic valves help to achieve better temperature control and cooling is more effective.
  • Since it is automatic in nature, there is no need for a person to be employed to physically operate the valves, thus it leads to savings in terms of labor and time – this translated to savings in money.
  • Easy addition of additional devices to the system without having an effect on balance.

Uses and applications of balancing valves

Automatic control valves have many uses and applications. It is commonly used in applications like:

  • It is used in HVAC (Heating Ventilation Air Cooling) systems used in large commercial and residential buildings to ensure temperature control.
  • It is used in chilled ceilings where a cooling effect has to be produced.
  • It can even be used in fan coil units.
  • It can be effectively used in any heating or cooling system where a balanced flow is needed.

Installation

Automatic balancing valves are very useful devices used in most cooling systems. When an organization wishes to buy and install these valves, they need to make sure they get it from one of the leading suppliers of Balancing valve. A well-known manufacturer and supplier would ensure quality in the valves. Durability and reliability are what one needs to look at while buying these valves.
